Infrared photodissociation spectra of acrylonitrile cluster ions

Research was conducted to examine the infrared photodissociation spectra of acrylonitrile cluster anions and cations using a coaxial infrared laser-ion beam spectrometer developed for the experiment. Ab initio calculation reveals that the cluster ion consists of a dimer ion core solvated with neural acrylonitrile molecules. The acrylonitrile cluster did not show any optical absorption in the wavenumber range studied.
